I discussed it with Wayne, he's hesitant to do a rechamber of a 45Colt barrel, he'll do a Casull tho. That probably would depend on how much it was shot, underlugs get set back in the 500 with hot loads around 52kpsi, hot loads in the 460 run up to around 57kpsi in the Hodgdon manual. The SAAMI MAP for the 500 is 60kpsi, 65kpsi for the 460, but I've not seen data push it to the MAP. It's another one like the 500, a great round in a pistol, but in a rifle, it's just does the same thing a 45-70 does with a bunch more pressure and bullets that aren't made for that kind of veliocity, IMHO.
